Example

This example shows how to bind a numeric chart range control client to a System.Collections.Generic.List containing NumericItem objects.

In order to provide data to a chart numeric range control client, you need to access the ChartRangeControlClientDataProvider object using the ChartRangeControlClientBase.DataProvider property and assign a data source to the ChartRangeControlClientDataProvider.DataSource property.

Each NumericItem object contains Argument, Value and Series properties, to which a numeric chart range control client is bound via its ChartRangeControlClientDataProvider.ArgumentDataMember, ChartRangeControlClientDataProvider.ValueDataMember, and ChartRangeControlClientDataProvider.SeriesDataMember (optional) properties.

In addition, this example shows how to customize chart client common settings (e.g., change the numeric range, customize template view and grid options).
